BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 773,891, dated November 1, 1904. Application filed January 21, 1904. Serial No.'l90,004. (N model.)

To all whom, it may concern.-

. Be it known that I, JOHN W. PERTZ, a citizen of the United States, residing at Elwood, in the county of Madison and State of Indiana, have invented new and useful Improvements in Brick-Machines, of which the following is a specification.

This invention relates particularly to brick or block machines in which the bricks are formed and pressed in facial molds made in a continuously-rotating table, the pressure being effected by plungers operated by cams underneath the table.

The object of the invention is to produce, first, an improved pressure mechanism; second, an improved ejector mechanism; third, an improved take-ofi or conveyer mechanism cooperating with a novel form of plunger which lifts the bricks, so that the conveyer can take them, and, fourth, an improved adjusting mechanism to regulate the pressure and size of the bricks.

Further advantages and improvements of construction will be apparent from the following description and the accompanying drawings.

In the drawings, Figures 1 and 2 are side elevations of the machine. Fig. 3 is a central vertical section. Fig. 4: is a top plan view. Fig. 5 is a plan view showing the bedplate and the driving and adjusting gear, the table and plunger being removed. Fig. 6 is a sectional View in diagram or projection showing the cam construction and action.

Referring specifically to the drawings, A indicates the circular rotary table in which are formed a circular series of openings to receive the plungers 1. ed to the face of this table over the openings, and secured and supported on top of the molds is a cover or upper plate 3 of the table, forming a smoothtop having openings corresponding to the molds. To properly support this top, it rests on shoulders 3 in the molds. A rotary pressure plate or wheel 4is supported at one side of the table and in close contact with the surface thereof and over the molds by a heavy strong arch or frame 5, which has at the top a bearing to receive the gudgeon driven in any suitable manner.

The molds 2 are boltor stem 4 of the pressure-plate. This plate gets its motion from its friction with the table,

so that it turns with the table over the upper surface of the block in the mold. The arch holds the pressure-wheel firmly to the table and sustains the thrust of the plunger.

The main vertical shaft is indicated at 6, set in a stepped bearing 12 at the bottom, and the table is keyed on this shaft between adjustable nuts 7. Under the table the shaft carries a bevel-wheel 8, in gear with a drivingpinion 9 on the drive-shaft 10, which may be The rotation of the table is thus effected in an obvious manner. The shaft 10 is mounted in bearingboxes 17 At 11 the pressure-cam wheel is shown. This is fixed on the shaft 10 and has cam-surfaces in proper number and position to engage under the lower ends of the plungers and lift the same to press the bricks in the molds. The plungers travel otherwise on the track 13, supported by standards 13. They slide vertically in guides 25, bolted to the under side of the table.

At the ejecting-cam wheel is indicated. The short shaft of this wheel is supported in suitable bearing-boxes 17 and carries a bevelpinion 30, in gear with the bevel-wheel 8, heretofore referred to. The ejecting-wheel has appropriate cam-surfaces and is of sulficient size to lift the brick above the surface. of the table-top. To lift the brick farther in position to be taken off by a belt-conveyer, to be described hereinafter, the plunger is provided with a rod 14., which works lengthwise in a bore therein and has at the top a head 1r" on the upper end ofv the plunger. The lower end of the rod has a T, as indicated at 1A, the branches of which extend laterally through and work in a slot 16 in the'lower end of the plunger, and these branches carry rollers 15, which, after the plunger is lifted by the ejecting-cam 80, mount and ride over a cam-track 27, arranged and supported in sists of two belts 21, which are spaced apart a suflicientdistance to allow the passage therebetween of the rod 14. These belts pass over the rollers 21, journaled on a suitable bracket 22, so that the forward or taking end of the belt extends over the top of the table in line with the line of molds. The belts may be driven in any suitable manner.

The shape of the cam-track 27 is such that the rod 14: is lifted just before the brick reaches the conveyer-belt. This raises the brick above the conveyer-belts, the stem 14 passing be tween said belts. W' hen the drop 27 in the cam-track is reached, the rod drops and the brick is deposited on the conveyer-belt. This action is repeated with the successive plungers, and an automatic take-off is thus produced having highly effective action.

A support for an upper bearing 18 for the table-shaft 6 is afforded by bar 18, projecting from the top of the arch 53 At 20 a feedhopper is shown, supported by an arm 23, projecting from the collar or bearing 18.

The feed-adjusting mechanism of the machine is clearly indicated in Figs. land 2 and comprises the shaft 24*, operated by handwheel 24" and carrying a Worm 24:, in mesh with gear-wheels 28, which have screw-shafts 28, which enter threaded .bores in bosses 29 on the under side of the adjusting-plate 29, which plate forms a part of the track for the plungers and is located directly under the hopper 20. By means of the worm andgearing the plate may be raised or lowered, which varies accordingly the size of the mold, and consequently the amount of material fed therein from the hopper.

To regulate the size of the brick and also the degree of pressure, the table may be raised or lowered with respect to the plunger. As heretofore stated, the table A is keyed to the shaft 6; but it has vertical motion thereon, controlled by the adjusting-nuts 7. \Vhen the nuts are raised or lowered, the table is raised or lowered accordingly. Necessarily the pressure-plate 4 must have similar vertical adjustment. To effect this, the bearing of the arch 5 for the stem 4 is split, as indicated at 5, and thread ed to receive the threaded bushing 5 The bushing, and conse quently the pressure-plate, may thus be adjusted in the arch, and when set the adjustment is fixed by the jam nut or collar 5 on the upper end of the bushing and by bindingbolts 5, connecting the split sections of the arch. A

The general operation of the machine is not substantially different from the well-known continuous rotary mold-block presses. The drive-shaft 10 produces the rotary motion of the table, the clay or other material being fed from the hopper 20 into the molds as they pass thereunder. The plungers travel along their track until they reach the pressurewheel 11, by the cams of which they are lifted to compressthe blocks against the pressureplate f. They are then lifted by the ejectingwheel 30, and thereafter in a continued rotation of the table the bricks are lifted and deposited on the conveyer-belts by the action of the rod 14, produced by the cam-track 2.7, after leaving which the plungers drop to the original track for the next operation.

\Vhat I claim as new, and desire to secure by Letters Patent, is-- 1. In a brick-machine, the combination with the rotary table having molds and plungers therein, of the rotary pressure-wheel supported over the molds.
